Maire Tecnimont S.p.A. announced that its subsidiary Tecnimont S.p.A. has been awarded by Yara International ASA (Yara) an EPC contract for a new urea granulation plant to be implemented in Sluiskil, The Netherlands.

Fernanda Amaral, an MU postdoctoral fellow and researcher in the Bond Life Sciences Center, found that less dependence on nitrogen could start with a simple type of grass, Setaria viridis, and its relationship with naturally occurring bacteria.

Louisiana Governor Bobby Jindal and board Chairman Arunas Laurinaitis of Lithuania-based Investimus Foris announced the company will make a $265 million capital investment to convert an idle biofuels refinery in Grant Parish into an ammonia manufacturing facility.

The 2015 Illinois corn crop continues to develop on schedule, with 75% of the crop having reached silking by July 19. But the crop condition rating continues its steady downward trend, with the good + excellent percentage now at 55%, down from its high of 79% at the end of May. Virtually all of this decline is due to standing water, past or present.

It is a well-known fact that rainfall has a lot do with nitrogen loss in Iowa fields. What was not clear before, was how rainfall could be used to determine if a certain field would be nitrogen (N) deficient. The recent influx of different predictive N tools has spurred renewed interest in using rainfall for assessing the risk of corn N stress or the likelihood of a yield response to N fertilizer.

Rain. Rain. Rain. With excessive rain, chances are good most fields across Indiana have lost more N than in a typical year. But how much have they lost? Everything applied? Is all of the N fertilizer gone? Although it’s difficult to estimate, it’s very unlikely that the majority of the N applied has been lost.

In North America, there is a perception among many urban dwellers, and even many in agricultural communities, that observance of nutrient deficiencies in leading field crops like corn, sorghum, soybean, wheat, cotton, and rice is relatively rare. Yet it is important to recognize, by the time plant nutrient deficiency symptoms are visually observed, significant crop yield has been lost and soil productivity has been compromised.

Heavy rainfall over the past several weeks has left many producers across the state with few opportunities to side dress their corn with nitrogen. To make matters worse, excessive water means that significant soil nitrogen has likely been lost through denitrification and/or leaching.

On the first of June, it looked like there would probably be a few corn fields with nitrogen problems in Missouri. Now, on the first of July, it looks like there will probably be a few corn fields that don’t have nitrogen problems. All but the southeastern corner of the state has received more than 12 inches of rain in May and June.
